Interaction of a dipole with an interfacial crack in piezoelectric media (2005)
Gao, Cun-Fa, Tong, Pin, Zhang, Tong-Yi
We have studied the interaction of an electric dipole with an interface crack between two dissimilar piezoelectric materials. The solutions are derived based on the Stroh formalism. Three crack...
Fracture mechanics for a mode III crack in a magnetoelectroelastic solid (2004)
Gao, Cun-Fa, Tong, Pin, Zhang, Tong-Yi
In this paper, we developed a Stroh-type formalism for anti-plane deformation and then investigated the fracture mechanics for an elliptical cavity in a magnetoelectroelastic solid under remotely...
Gao, Cun-Fa, Zhao, Minghao, Tong, Pin, Zhang, Tong-Yi
In this work, we examine the energy release rate and the J-integral of an electrically insulated crack in a piezoelectric solid under remotely uniform electrical/mechanical loads. We model the crack...
Zhu, Mei-Ling, Lee, Ricky Shi-Wei, Li, Hing Leung, Zhang, Tong-Yi, Tong, Pin
In this paper we present a dynamic analytical model for the torsional vibration of an anisotropic piezoelectric laminate induced by the extension-twisting coupling effect. In the present approach, we...
Lakshmikantham,Chatta, Tong,Pin
This paper deals with an analytical determination of the stress field around a symmetrically placed hole whose shape is one of a circle or an ellipse. The hole is in an orthotropic panel (strip)...
Effects of electric fields on the bending behavior of PZT-5H piezoelectric laminates (2000)
Cheng, Jinquan, Qian, Caifu, Zhao, Minghao, Lee, Ricky Shi-Wei, Tong, Pin, Zhang, Tong-Yi
This paper investigates the bending behavior of piezoelectric laminates under combined mechanical and electrical loads. The laminates have a PZT-5H ceramic core sandwiched between two graphite/epoxy...
A variational principle is formulated as the foundation of the finite-element method proposed by Pian. Through this formulation an extension of Pian's original proposal is made and the convergence of...
Variational Formulation of Finite-Displacement Analysis, (1998)
Derivations of several variational principles for the incremental large deformation problems are made based on the second variation of the variational functionals. Finite element analyses using...
Stability of Transient Solution of Moderately Thick Plate by Finite-Difference Method. (1998)
The condition of stability of the finite-difference equation for the transient response of a 'moderately thick' plate is derived. The effect of transverse shear and rotatory inertia on the stability...
Static and Dynamic Nonlinear Structural Problems. (1998)
The objective of this research is to develop mathematical tools for determining stresses, deformation, and stability of aerospace vehicle structures. The nonlinear structural behavior, such as...
Rationalization in Deriving Element Stiffness Matrix by Assumed Stress Approach (1998)
From the principle of minimum complementary energy, which is extended to take into account the possible discontinuity in stresses or displacements along the interelement boundaries, the finite...
Emission of an edge dislocation from a thin-film-covered crack (1998)

Mechanical property study of composite grid reinforced concrete (1996)
Chen, Ming, Li, Zongjin, Lee, Ricky Shi-Wei, Tong, Pin
Most deteriorations of structural concrete can be attributed to corrosion of reinforcing steel. The extent of the problem caused by corrosion is so serious that concrete durability has been recently...
